i790 alt 'whom it may concern:

Be it known that I, ERIK F. CARLSON, aA

Kings, city and State of New York, have invented certain new and useiul Improvements in Revolving Telephone Stands, ot which the following is a specification.

The main object of this invention is to provide a rotatable table or stand adapted to carry a number of telephone sets permanently attached thereto and so arranged that lthe table rnay be readily rotated in either direction to bring the desired telephone set into convenient position :tor use.

Another object of the invention is to provide a rotatable stand adapted to carry a number of telephone sets and to so construct the stand that it rnay be rotated only once in either direction; and also to provide ine'ans whereby there will be suflcient slack in the telephone wires enclosed within the table or Stand to -perinit of a movement ot the telephone stand in either direction to bring the desired telephone into position for use.

A further object of the invention is to provide a rotatable stand for the purpose set forth which shall be simple in construction and to which the telephone sets may be easily and quickly attached and where there will be no loose wires or cables visible eircept, of course, the cable connecting the receiver to the transmitter base.

In the drawing, F ig. 1 isa perspective view of the device complete, showing a series of telephone sets secured thereto;

Fig. 2 a vertical central sectional view of the stand, the telephone sets being removed; and y Fig. 3 a plan view of the stand as illusl trated in Fig. 2, with the telephone sets removed.

Referring to the various parts by numerals, l designates a circular platerwhich forms the base oi the stand and said base -is formed with a central upwardly extending tubular boss-2. This boss is internally i threaded, and screwed into it is a tubular standard 3. On the base, and surrounding the lower end of the tubular standard, 1s an ornamental wooden base piece 4. Mounted on the upper end of the standard 3 is a head l5. This head may be of `any suitable inaterial; as shown itis made of wood and Serial No. 512,601.

to its bottoni is secured an internally threaded `ianged connecting ring 6, saidV ring being threaded to the upper end ot the standard 3 and rigidly connected to the head by screws or other fastening means passing through its flange into the lower portion ot the head. The upper surface oi the head is horizontal and substantially circular, and in said upper surface is formed a deep annular channel or cavity 7. rhis `cavity is curved downwardly toward the vertical axis of the head so that its lower portion is almost directly over' the hollow standard 3. This cavity is ci considerable width in order to give it the desired capacity for holding a considerable length of telephone cable, for a purpose which will be hereinafter described. Secured to the top of the head, and centrally located thereon, that is to say, with its center axiallyin line with the center of the standard 8, is a bearing plate 8. This bearing plate is formed near its circumference with a ball race 9 and at its center with a depending internally threaded socket 10. This bearing plate is secured tothe head by means oi screws 11.

Mounted centrally on the head is a rotatable circular table 12. ln the under side of the table is mounted a circular bearing plate 13, said plate being secured to the table by means oi screws 11i. rlhe plate 13 is formed with a ball race 15 which is complernentary to the race 9 of the plate 8; and in these two raceways are mounted bearing balls 16. The table is connected to the head by means of a shouldered screw 17. This shouldered screw is provided with a threaded end adapted to screw' into the threaded socket 10 and also with a head 18 at its upper end which is adapted to en gage the upper surface of the bearing plate 13. The shoulder 19 ot this screw bears against the upper surface or' the plate 8 and the` head of the screw overlies the bearing plate 13 and serves to hold the two bearing plates in their properly assembled relation. The head ot the screw does not bind on the plate 13, so that said plate and the table connected thereto may freely rotate about the screw,'said screw serving as a connecting means, but not as a clamping means. When it is desired to have access to the telephone cables within the stand, the table may be readily disconnected from the upper suitable form.

bearing plate by removing the screws la. By this means telephones may be connected to or disconnected from the stand without vdismantling or disarranging the parts of lthe ball bearing'support. y

In the under side of the table is formed an annular groove 20. ln this groove is arranged a stop 21. This stop may be of any As shown n the drawing, it is formed by interrupting the groove. llt is-manifest, however, that it may be formed Lin any suitable way. Rigidly secured to the upper surface of the head is a pin 22 which lits loosely in the groove 20. This pin serves as a means to limit the rotation of the table, but permits it to have a substantially com- `*plete revolution in each direction. The purpose of this isl to permit the table to be rotated vin either direction to bring the desired telephone set into position for use, and to prevent a complete rotation of the ltable which, ofcourse, would damage the telephone cables and cause the table to jam and l become inoperative.

Vvided with a series of apertures 2i which register with thel upper end of the channel 7, as shown clearly in Fig. 2,y and the cables containing the telephone wires are passed upwardly through the apertures 24, and

thence to the base of the telephone transmitter.

On the table a series of clamps 25`are secured, said clamps being designed to receive the base portion of the ordinary tele-y phone stand. These clamps may be of any suitable construction. As shown in the drawings, they consist of a base having three radial arms to the `ends of which are adjustably secured clamping lugs 26. rllhese lugs are adjustably` connected to the base of the clamps by screws 27. llt is obvious that by manipulating the screws and the clamp lugs" theiordinary telephone stand may be quickly attached to or detached from the holding means.

(itl

, tendin Secured to the head 5 is a laterally exarm 28 whose upper surface is substantia ly flush with the upper surface of the .table and is adapted to serve as a pad supporting-means. It is obvious that this pad supporting means may be dispensed with if desired; and also that it may be of any suitable form and of any desired construction.

Ay telephone stand constructed in accordance with this invention is especially adapted for'use where a number of telephones areV sets individually. The table may be almost instantly rotated to bring the desired telephone into position for use, and then it is necessary for the operator to merely remove the receiver from the usual supporting hook.

lt, of course, will be understood that any desired number of telephone sets may loe mounted on the table and that the table will be made the proper size to adapt it for the use for whichv it is intended. t is also manifest that any suitable means maybe used for connecting the table top to the noniotatable head. rihe means `shown is convenient and simple, but-may -be varied as desired. Any suitable formof support may be used for the head.

`What I claim is: A

A telephone stand comprising a stationary tubular standard, a stationary head rigidly supported thereon and formed with an annular cavity extending downwardly from the upper surface thereof, the upper end of the cavity being open, said head also being formed with apertures connecting the lower end of said cavity with the interior of the tubular standard, a table rotatably mounted on the head and formed with a series of apertures registering with the upper open end of the cavity in the head, and means permitting the table vto have one subf stantially complete revolution in either di`- rection'. y l f 2.
